- the condensed water is then generally in a suitable Collected container and the cooled and dried air again the heater (which may be the heat source of a heat pump) and then fed to the drum
- this drying process is very energy-intensive, since the cooling air flow heated in the heat exchanger during cooling of the process air can be lost energetically.
- a heat pump By using a heat pump, this energy loss can be significantly reduced.
- the cooling of the hot, with moisture laden process air substantially in a heat sink of the heat pump, where the heat extracted from the process air, for example, used to evaporate a refrigerant used in the heat pump cycle The heat absorbed in the heat sink is transported within the heat pump to the heat source and there again - possibly at opposite to the temperature the heat sink of elevated temperature - given off again

- the liquefied refrigerant eventually flows through a throttle back to the evaporator; the throttle is used to reduce the internal pressure in the refrigerant, so that it can evaporate in the evaporator with renewed absorption of heat.
- the heat pump which is thus operated with a circulating refrigerant, is also known as a "compressor heat pump.” Other types of heat pump are also known.
- DE 40 23 000 C2 discloses a clothes dryer with a heat pump, in which a supply air opening is arranged in the process air channel between the condenser and the evaporator, which is closable with a controllable closure device.
